Leschenaultia hybrid variety `Ultraviolet`
ORIGIN OF THE VARIETY 
     This variety arises from the controlled pollination in July 1986 at the Horticultural Research Station, Gosford, New South Wales of a Leschenaultia formosa plant (seed), Breeders Accession No. 6, by a Leschenaultia biloba (pollen) plant. Seeds were germinated and a seedling selected for flowering duration and the size and color of its flowers. Subsequent plants have been propagated asexually from that seedling by tissue culture and stem cuttings. The subsequent plants produced possess all the characteristics or come true to form with the original plant and the characteristic features are firmly fixed and maintained in the succeeding generations of plants. 
     SUMMARY OF THE VARIETY 
     &#34;Ultraviolet&#34; is a small bushy erect herbaceous perennial plant up to 37.0 cm tall. The foliage is dense with small green fleshy leaves crowding the stems. The flowering season of &#34;Ultraviolet&#34; is from April to October in the southern hemisphere. Flowering is from autumn through to late spring in protected cultivation. The five winged petals are violet blue paling at the center to mauve. The corolla tube has both a basal tuft and lining of hairs internally. &#34;Ultraviolet&#34; is a fertile plant and is suitable as a potted flowering ornamental. 
    
    
     DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying photographs show typically: 
     (i) the plant-form and size and the size of flowers; 
     (ii) the size and color of the &#34;Ultraviolet&#34; flower (left) relative to a Leschenaultia biloba flower (right). 
     The colors are as nearly true as reasonably possible in color representations of this type. 
    
    
     DESCRIPTION OF THE VARIETY 
     In the following botanical description color references are made to the Royal Horticultural Society Colour Chart. Descriptions are based on observations made during August 1988 of 20 randomly selected, 12 month old well-fertilized potted plants growing in open-sided unheated polyethylene greenhouses at the Horticultural Research Station, Gosford New South Wales, Australia.

     COMPARISONS WITH OTHER KNOWN SIMILAR VARIETIES OF LESCHENAULTIA 
     The pollen parent L. biloba is a commercially available unnamed variety in the New South Wales nursery industry. 
     The seed parent L. formosa Breeders Accession No. 6 was collected from the wild. 
     The observations for the comparisons were made under the same circumstances as those for the Description of the Variety. 
     &#34;Ultraviolet&#34; has violet blue and mauve flowers, 94A outer and 75A center, when fully opened while L. biloba&#39;s flowers are blue, 99B outer and 99C center, when fully opened. 
     &#34;Ultraviolet&#34; flowers from Autumn through to late Spring while L. biloba is in flower during Winter/Spring. 
     &#34;Ultraviolet&#34; has a slightly curved style compared with a pronounced curved style for L. biloba. 
     &#34;Ultraviolet&#34; has erect upper petals while L. biloba has spreading upper petals. 
     &#34;Ultraviolet&#34; has ciliate margins and a dense tuft of hairs at base of inside of corolla tube compared with ciliate margins only for L. biloba. 
     &#34;Ultraviolet&#34; has a longer corolla tube mean 11.61 mm, than L. biloba mean 8.38 mm. 
     &#34;Ultraviolet&#34; has red pigmentation at the base of mature leaves compared with L. biloba which has none. 
     &#34;Ultraviolet&#34; has violet blue and mauve, 94A outer and 75A center, flowers when fully opened while L. formosa, Breeders Accession No. 6, has Orange 28A whole flowers when fully opened. 
     &#34;Ultraviolet&#34; has an erect and straggling habit while L. formosa, Breeders Accession No. 6, has a prostrate habit. 
     The new variety is easy to propagate using either stem cuttings or tissue culture methods. Hardening off of rooted plants takes 2-3 weeks. Production of a flowering pot takes 16-18 weeks.
